UNITED STATES PATENT I GEEIC HIRAM It. SAVAGE, OF SARDINIA, NEW YORK.

CREAM-SKIMMING DEVICE.

SPECIFICATION forming part of Letters Patent No. 361,720, dated April 26, 1887. Application filed July 8, 1886. Serial No. 207,438. (no molel.)

such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The object of this invention is to automatically skim milk and draw off the cream from the top, (without using dippers, skimmers, &c.,) and by which milk is prevented running in with the cream and time saved.

The invention as constructed and applied will be understood by reference to the following specification and claims:

I11 the drawings, Figurel isa sectional View of the whole device; Fig-2, detail of tubes in section and rubber-ring packing; Fig. 3, detail of pail-gage.

A represents a pail or receptacle holding milk for raising cream, and having a creamgage, a, on the side.

I) is a permanent central tube open clear through and ending about midwayin the pail, as shown. Inside this is another open tube, 0, sliding up and down therein. The necessary tight connection is made by two round rubber rings 6 0, set around the tube 0, leaving an airspace, f, between the rings, preventing water coming between the tubes when set in a cooler or milk passing down when set for cream.

The pail Ais set on the bottom or shelf (1 of a wooden stand, B, which has also a central opening therein corresponding to the opening of thetube b, the object to be presently explained.

On the top of the stand B is a simple framework fastened thereto, consisting of uprights, h h, a central guide, 43, and a verticallyacting pressure-bar or plunger, k, operated by a pivoted handle, m, (or by any suitable simple device,) for raising and lowering the bar, which projects through the guide 2', table 9, and paileover 10 into the pail A. Its lower end is provided with claws or fingers 7c, fitting on the rim of the tube 0, asin Fig. 1. The openings are to allow the cream to run through into the tube a.

On the bar 70, above the table 9, is a gage, a, figured from the bottom 1, 820., to top, in contradistinction to gage a on the pail, which is marked 1 at top. and numbered on down, so that when a stop "or peg, s, is set in gage a it is for a purpose now to be explained in the operation and working, which is as follows:

The receptacle A, holding the milk, is set in the stand B, the tube a being raised above the milk surface and the bar k resting on the rim. When the cream has fully set, the gage a is consulted, and the figure thereon which the depth of the cream reaches is noted. Then the peg s is set in the bar It at a figure corresponding to that on the cream-gage, and the bar pressed down by the handle m as far as the peg allows, which forces down the inner tube, 0, until it stops at the exact depth of the cream, as noted by the gage a, the gage a'having been arranged on the bar 70 to bring about exactness by the placing of the peg and its striking the crossbar t of the framein accordance therewith. This causes all the cream on the surface of the milk to run from the top into the tube a, and down through tube b, bottom d, and into a cream-receiver, 0, set beneath, (see Fig. 1,) leaving the milk standing in pail A on an exact level with the top of the tube a. It takes but a moment for the cream to run out, and it does not carry any milk with it. Then the pail A is taken out and another setin the stand B and treated in the same manner, and so on through anynumber.

As'the amount of milk and cream varies at different times and in different pails, it is only necessary to set the bargage a by the one on the pail to get accurate results.

By ordinary skimming, &c., an amount of milk must get in with the cream, while by this device it is almostimpossible. This will prove a great advantage, as when the cream-gatherer examines the gages he sees and can note the amount of cream he can depend on before it is drawn off, and when my device is used the cream obtained will correspond with his tally.

The tube 0 is drawn up and out by hand,

and is removed, so as to thoroughly clean the parts.

I claim 1. The combination of a milk and cream receptacle, A, having a cream-gage, a, the permanent open tube 1), tube 0, sliding therein, and the pressure-bar 7;, having fingers k, in connection with said tube a, all substantially as and for the purpose specified.

2. The combination of a milk and cream receptacle, A, the permanent open tube 7), and independent tube 0 sliding therein, and the pressure-bar 7c, having a gage, a, in connection therewith, said bar operated in connection With-the tube 0 by the pivoted handle m, all substantially as and for the purpose specified.

3. The combination, in a milk and cream receptacle, of the permanent open tube 1), the independent tube a sliding therein, the pressure-bar is, having fingers is, operated in connection with tube 0, thestop s, and cross-bar i, all substantially as and for the purpose specified.

4. The combination of the stand B, having an open bottom, d, the milk-receptacle A, provided with the gage a, and tubes 12 c, the pressure-bar k, having the gage a and fingers 7c, operated by the handle m, and the cream-1eceiver 0, all substantially as and for the purpose hereinbefore fully explained.

Intestimoriyjwhereof I affix my signature in presence of two'witnesses. v
